Title: Sliding contact point material for vacuum device
Inventor: HARA KENJI
IPC: C22C27/04
Filed: 1986-03-03
Abstract: PURPOSE:To obtain a contact point material capable of impressing a bias voltage stably for many hours without causing increase in electric resistance, by constituting a sliding contact point for supplying a bias voltage in a vacuum device forming thin films of specific percentage of W and Ag. CONSTITUTION:In the vacuum device forming thin films in vacuum by sputtering, ion plating, etc., the contact point for sliding for bias voltage supply is composed of a W-Ag alloy containing 30-80% W prepared, e.g., by a sintering process. In this way, the increase in contact resistance caused by seizure is prevented, so that bias voltage can be impressed to the sliding contact point part stably for many hours.

Title: Boosting circuit
Inventor: KANEKO SHOJI
IPC: H03K19/094
Filed: 1987-02-26
Abstract: PURPOSE:To improve the reliability of the titled circuit by providing a timing circuit bringing a gate potential of an NMOS transistor (TR) provided between a power supply and an output terminal is brought into a high level after the output boosting. CONSTITUTION:With an input signal changed from a high level to a low level, the potential of the output signal is boosted to a power potential or over by the output of a CMOS inverter 1. While the potential of a gate N2 of the TR Q2 is kept to a low level, when the boosting is finished, the potential goes to a high level by a timing circuit 10. If a TR Q3 is turned on momentarily, the potential of the output signal is deceased and the gate-source voltage of the TR Q2 reaches the threshold voltage, the TR Q2 is turned on and the output terminal is charged. Then the potential of the gate N2 of the TR Q2 rises over the power potential and the potential of the output signal is kept to the power potential. Thus, the output level is compensated and the reliability of the circuit is improved.

Title: Fm communication equipment
Inventor: UMAZAWA HIDEKI
IPC: H04B1/10
Filed: 1990-02-27
Abstract: PURPOSE:To easily eliminate a squelch tail period by putting off a power after lapse of an operation delay time of a tone squelch detection function after a tone is lost at the end of talking. CONSTITUTION:As soon as a PTT(press-to-talk) switch is closed similarly to a conventional system at talking from a transmitter side, tone and power are transmitted. The transmission of a tone is deenergized when the PTT is opened at the end of talking and the transmission of power is deenergized after lapse of the operation delay time (t) of the tone squelch detection function of the receiver. Thus the circuit sending a signal while the phase and frequency of the tone are varied to eliminate the squelch tail period is not required for the transmitter and the circuit detecting a change in the tone is not required for the receiver. Moreover, a time after the output of tone and the PTT are opened till the transmission of power is tuned off has only to be the operation delay time (t) of the tone squelch detection function of the opposite receiver or over, a time of 180msec is in general enough.
